Definitions

  • the present invention relates to a cosmetic product with smoothing effect and rubbery texture which turns into powder when applied, as well as to the process for obtaining the same.
  • the aforesaid cosmetic product may be used as a smoothing-effect, shine-free makeup foundation.
  • a cosmetic product of this kind which uses polymethylsilsesquioxane in association with silicone oils as basic ingredient, is already commercialized.
  • This product appears in the form of compact powder which, once applied, conceals pores, absorbs sebum in excess and reduces oiliness in excess without causing weals or leaving white residues on the skin.
  • US 2007/098661 A1 discloses powder putties which uses corn starks as cosmetically accepted powder.
  • US 2005/112072 A1 discloses a silicone gel comprising a hybrid polymethylsisesquioxane (PMSQ)/polydimethylsilozane powder.
  • PMSQ polymethylsisesquioxane
  • a cosmetic product with smoothing effect characterized in that it comprises:
  • polymethylsilsesquioxane used is Tospearl 3000 A PC from Momentive.
  • the silicone oils and resins may consist of:
  • dimethicone with low viscosity e.g. from 10 to 350 cst
  • dimethicone and dimethicone crosspolymer used is D.C. 9041 from the same manufacturer.
  • Active ingredients may be present.
  • the product is obtained by extruding a paste created by mixing the above-described ingredients, followed by cutting and pressing into containers.
  • Main features of this product are the absolute transparency thereof and the change of texture during its application, because once taken by means of a specific applicator it turns from rubbery into powder.
  • the product is obtained by premixing the liquid or semi-liquid or pasty ingredients in a specific mixer equipped with planetary blades along with possible pigments and active ingredients, such as vitamins, solar filters, antioxidants.
  • the powder phase consisting of polymethylsilsesquioxane is then added and subjected to further mixing until an extrudable paste is formed.
  • the product thus obtained is in the form of a white paste which becomes transparent when it is extruded.
  • the extruded product is put into specific containers and pressed.
